The U.S. Environmental Protection Agency (EPA) has created the Environmental Technology
Verification (ETV) Program to facilitate the deployment of innovative or improved
environmental technologies through performance verification and dissemination of information.
The goal of the ETV Program is to further environmental protection by accelerating the
acceptance and use of improved and cost-effective technologies. ETV seeks to achieve this goal
by providing high-quality, peer-reviewed data on technology performance to those involved in
the design, distribution, financing, permitting, purchase, and use of environmental technologies.

ETV works in partnership with recognized standards and testing organizations; stakeholder
groups, which consist of buyers, vendor organizations, permitters, and other interested parties;
and with the full participation of individual technology developers.  The program evaluates the
performance of innovative technologies by developing test plans that are responsive to the needs
of stakeholders, conducting field or laboratory tests (as appropriate), collecting and analyzing
data, and preparing peer-reviewed reports. All evaluations are conducted in accordance with
rigorous quality assurance (QA) protocols to ensure that data of known and adequate quality are
generated and that the results are defensible.

The Air Pollution Control Technology Verification Center (APCT Center), one of six centers
under the ETV Program, is operated by RTI International (RTI), in cooperation with EPA's
National Risk Management Research Laboratory.  The APCT Center has evaluated the
performance of an emissions control system consisting of a fuel formulation and additive.

ETV TEST DESCRIPTION

All tests were performed in accordance with the Test/QA Plan for the Verification Testing of
Alternative or Reformulated Liquid Fuels, Fuel Additives, Fuel Emulsions, and Lubricants for
Highway andNonroad Use Heavy Duty Diesel Engines and Light Duty Gasoline Engines and
Vehicles and the Test-Specific Addendum to ETV Mobile Source Test/QA Plan for Flint Hills
Resources for the CCD15010 Diesel Fuel Formulation. These documents are written in
accordance with the applicable generic verification protocol and include requirements for quality
management, QA, procedures for product selection, auditing of the test laboratories, and test
reporting format.

The mobile diesel  engine air pollution control fuel formulation was tested October 18-27, 2006,
at Southwest Research Institute. The performance verified was the percentage emission
reduction achieved by the fuel formulation for particulate matter (PM), nitrogen oxides (NOX),
hydrocarbons (HC), and carbon monoxide (CO) relative to the performance of the same baseline
engine with standard ultra-low sulfur diesel (ULSD) fuel. Operating conditions were
documented and ancillary performance measurements were also made. A summary description
of the ETV test is provided in Table 1.

VERIFIED TECHNOLOGY DESCRIPTION

This verification statement describes the performance of the tested technology, CCD15010 diesel
fuel formulation with H1TEC4121 additive, on the diesel engine identified in Table 1.

VERIFICATION OF PERFORMANCE

The CCD15010 fuelformulation with HiTEC4121 additive achieved the reduction in tailpipe
emissions shown in Table 2 compared to baseline operation without the additive.

The APCT Center QA officer has reviewed the test results and quality control data and has
concluded that the data quality objectives given in the generic verification protocol and test/QA
plan have been attained. EPA and APCT Center QA staff have conducted technical assessments
of the test laboratory and of the data handling. These assessments confirm that the ETV tests
were conducted in accordance with the EPA-approved test/QA plan.

This verification statement verifies the emissions characteristics of the CCD15010 fuel
formulation with HHEC4121 additive for the stated application. Extrapolation outside that range
should be done with caution and an understanding of the scientific principles that control the
performance of the technology. This verification focuses on emissions.  Potential  technology
users may obtain other types of performance information from the manufacturer.

In accordance with the generic verification protocol, this verification statement is valid,
commencing on the date below, indefinitely for application of the CCD 15010 fuel formulation
with HiTEC4121 additive within the range of applicability of the statement.
